To achieve Clean + Planet Positive status at Sephora, a brand must fulfil various sustainability criteria, including commitments to climate actions, sustainable sourcing, responsible packaging, and environmental contributions.

Disclaimer: We include the nuances! 
It was a deliberate choice to filter in the nuances. This means we don’t just include certified accreditation but also unregulated terms and commonly used jargon. We chose to do this in order to gain a more rounded picture of each brand, aiming to enhance the validity and reliability of our understanding of their ethical stance.
